利用py-gc/ms研究温度和时间对生物质热解的影响
, PP. 845-849
Keywords: 温度,时间,py-gc/ms,裂解
Abstract:
？以稻壳为原料,采用py-gc/ms装置对其在不同热解条件下进行快速热解,并对热解气进行在线检测分析,考察了热解温度和时间对生物质热解性质的影响.结果表明,低于450℃,随着温度的升高,生物质热解产物种类及其产率均增加,但低温条件下产物种类较少,有利于产物的分离提纯;高于450℃,生物质热解产物种类基本稳定,仅在产率上有所变化,当550℃时,收率最大.随着热解温度的升高,其对应的最佳热解时间缩短,且生物质低温热解时间延长时热解比高温解热时间缩短时热解更充分.
